SAFETY-WINDOW FOR LOCOMOTIVE-CABS.

' Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed October 7, 1918. Serial No. 257,164.

To all whom it may concern:

Be it known that I, EDGAR M. JUTKrNs, a citizen of theUnited States,residing at La Junta, in the county of Otero and State" of- Colorado,have invented certain new and useful Improvements in- Safety-Windows forLocomotive-Cabs, of which the following is a specification, referencebeing had to the accompanying drawings.

This invention relates to certain improvements in safety windows forlocomotive cabs, and it is an, object of the invention to provide awindow of this general character having novel and improved means wherebythe same may be readily and conveniently moved into an open or closedposition in accordance with the occasions of practice so that anengineman within the cab may have a clear vision of the trackway inadvance of the locomotive.

It is also an object of the invention to provide anovel and improvedwindow of this general type which may be easily opened and closed withbut little exposure of the engine crew to the elements, and which fullymeets with the requirements of the Interstate Commerce Commission of theUnited States. 7 Y r A further object of the invention is to provide awindow of this general character having novel and improved means wherebya broken glass may effectively and quickly be replaced. p

The invention consistsin the details of construction and in thecombination. and arrangement of theseveral parts of my im: provedwindow, whereby certain important advantages are attained and. thedevice rendered simpler, less expensive and otherwise more convenientand advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be better understood, I will now. proceedto describe the same with reference to the accompanying drawings,wherein: p

Figure 1 is a fragmentary View partly in elevation and partly in sectionillustrating a safety window constructedin accordance with an embodimentof my invention, the window being in an open position: a

Fig. 2 is a fragmentary view partly in elevation andpartly in sectionillustrating my improved window in closed position;

Fig. 3 is an enlarged sectional view taken through my improved window asherein described;

Fig. 4 is a view partly in elevation and partly in section illustratingthe operating member herein employed; I

Fig. 5 is a View in top plan of the link included in the operatingmechanism of the window.

Fig. 6 is a view in elevation illustrating a modified form of frameadapted to be em ployed in connection with my improved win dow, a partbeing omitted; and

Fig. 7 is a fragmentary view in elevation of the inner face of the outerportion of the frame as illustrated in Fi 6.

While in practice two wlndows constructed in accordance with anembodiment of my invention are tobe employed, one at each side of thecab, the present disclosure is limited to but one window and itsconcomitant parts. 7

As disclosed in the accompanying draw ings, D denotes a door of a welllmown type and which is arranged at the front of a locomotive cab at oneside thereof, and which is provided with a window opening W whichpermits a member of the engine crew to have a clear vision of thetrackway in advance of the locomotive. Coacting with the window W is asafety window S mounted for swinging movement in a horizontal plane andwhich moves into open position in a direc tion opposite to the movementof the door D when being opened. In other words, the window swings in adirection away from the boiler. of the locomotive so that when thewindow S is opened or partially opened, the draft entering within thecab through the opening W will be deflected by the window S toward theboiler so that the engineman will be protected against the resultantdraft.

In the present embodiment of my invention the window S has an endportion suitably secured, as at 3, to the flattened portion 2 of thevertically disposed rock shaft R, so that the window S will move inunison with and in the same general direction as the rock shaft.

The shaft R is rotatably supported at its opposite end portions by thebearings 4L bolted or otherwise affixed to the top and bottom portionsof the frame of the door D. p The shaft R is held against endwise movement through the medium of the .oollars 5 arranged upwardly of thebearings 4 and said collars 5 are aflixed to the shaft R by the cotterpins 6 directed through the collars and the shaft R.

In the present embodiment of my invention the upper end portion of theshaft lt is provided with. a rock arm 7 terminating in anupstanilingextension 8. The extension 8 is loosely directed through an eye 9 formedat one end portion of a link 10, and said link is held in appliedposition relative to the extension 8 through the medium of a collar 11fixed. to said extension below the link through the medium of a key 12.

The opposite end portion ofthe link is also provided with an eye 13which extends 15 within the kerf of the forked or bifurcated end portionof an elongated member or rod 15. Carried by the forked or bifurcatedend portion of the member or rod 15 is a pin let which is looselydirected through the eye 13 so that upon endwise movement beingimpartedto the member or rod 15 the rock shaftR will be caused-to rotatethrough the medium of the linklO and the rock arm 7.

The major portion of the member or rod 15 is round incross section, andthe end ortion of said member or rod remote from the shaft R isflattened as indicated at 17. Boltedor otherwise secured to the portion17 of the member or red 15 is a depending operating member Msubstantially at right angles to the member or rod 15.

The member M comprises an elongated member bent into the form ofa' Uwith the upper or freeend portions of the side members 18 overlyingtheopposite sides of. the portion "17 of the. membenor rod :15, and securedthereto by the bolts 19 or the like.

The member M affords a loop which bridges the horizontally disposedplate 20 secured at its opposite end portions to the blocks 21 suitablyanchored to the adjacent side or wall vofthe cab. The side members 18'of the member M are maintained in fixed spaced relation by the bolts-22,and one of said: bolts is adapted to seat within the notches 23 and,prodncedin the upper marginal portion of the plate 20, andwhich seatswithin said notchesby gravity. The coaction between themember M and theplate 20 permitsthe window S to be effectively-locked llll closed orfull open position, or: in various intermediate positions.

Suitably secured to thelower end. portion of the memben M is a fillerblock a 24: which isshapedtoa-lford a "comfortable hand grasp or hold sothat the desired endwise movement maybe imparted to the member or rod 15by a member of the engine crew with convenience and facility. 7

The-memberor rod 15 is also slidably disposedthroughaguide 25 suitablyattached to the adjacent side or wall of the cab, and which serves' as asupport for the forward end portiomof saidmember or-rod lo. 1t 65 willbe self-evident that the coaction between the member M and the plate 20will result inthe desired support for the rear portion ofsaid member orrod 15.

Ashereinset forth, the safety window S comprises a frame F substantiallyU-shaped in form. with longitudinal. membersa horizontally disposed. Theadjacent marginal portions of the frame are defined by inwardly directedflanges 26 and the outer end portions of the flanges of the side membersa are connected by the transversely disposed member 27 substantiallyU-shaped in cross section and having the outer side member Z) V of lesswidth than the inner side member 0 so that the insertion or removalof'the glass panel P may be facilitated and with the possibilityofbreakage of said panel during its insertion or removal in the frame 25substantially eliminated.

The lass )anel P when aolied has an end portion disposed between themembers Z) and 0 of the member 27" and also bears against the flanges26.

Between the longitudinal flanges 26 is a yokeQS having its free endportions pivotan ally engaged with said longitudinal flanges 26 throughthe medium ofclamping bolts 29 and the intermediate portion 30 isdefined by an inwardly directed flange 31 which, when the yoke 28 isswung inwardly of the frame 25 contacts with the end portion of thepanel P remote from the member 27. When the yoke 28 is in this positionit is held thereat by tighteningthe clamping bolts 29. When it isdesired to remove the 10 panel P for any cause, it is only necessary toloosen the bolts 29" and swing'the yoke 28 V outwardly. With the yoke 28in this position a new panel'P can be readily applied.

As is particularly illustrated in Figs. 6 106 and 7, I disclose amodified form of frame for use in connection with my, improved window,and wherein the bottom portion is partially cut away so that the lowerportionof the frame will afiord no obstruction 110 acrosslthe cab door.In theformi of invention as disclosed in Fig.1 6 the frame Fsubstantially rectangular in form with its lower longitudinal member a"cutaway throu, ;houtv its major portion so that when the frame overliesthe door or. more pan ticularly the panel thereof untilthe upperhorizontal a will obstruct the vision, The members a and 0 together withthe end members 7) of theiframe have their: outer margins defined by theinwardly. directed flanges 26. The inner member 6 isadapted to besuitably-attached to the rock shaft R and enacting with said connectedend portion of the frame F is a yoke 28: of substantially the sameconstruction and operating in substantially the same manner as the yoke28 hereinbefore referredto. Secured to the outer member 6 isaimember 27substantially U-shaped in cross section and otherwise simila' in.construction to the member 27 hereinbefore referred to.

From the foregoing description, it is thought to be obvious that asafety Window for locomotive cabs constructed in accord ance with myinvention is particularly well adapted for use by reason of theconvenience and facility with which it may be assembled and operated,and it will also be obvious that my invention is susceptible of somechange and modification without departing from the principles and spiritthere of, and for this reason I do not wish to be understood as limitingmyself to the precise arrangement and formation of the several partsherein shown in carrying out my invention in practice except ashereinafter claimed.

I claim:

1. In combination with a locomotive cab having a hinged door at thefront and one ide thereof, said door being provided with a windowopening, and a window supported for swinging movement in substantially ahorizontal plane and coacting with the window opening in the door, saidwindow and door having swinging movement in reverse directions.
